Description
Technical field
The present invention relates to a kind of fixture for clamping automobile tire, more particularly, to a kind of automobile tire fixture, belong to vapour
Car technical field.
Background technology
Toeing-in refers to the angle between vehicle body direction of advance and wheel plane, and two wheels viewed from above point to
Direction, a pair of front-wheel in front end is pointed to(Or trailing wheel)Toeing-in, outside sensing then be referred to as wheel posterior cord, before wheel
Bundle or posterior cord can be represented with inch, millimeter or angle;When automobile is for rear wheel drive, front-wheel generally has toe-in, and works as vapour
When car is front-wheel drive, front-wheel then posterior cord, this is the change in order to compensate steering gear connection and deflecting roller in vehicle traveling process,
When running car, prenex or posterior cord reduces or disappears, this is because return wanted in the presence of acceleration by wheel, turns to simultaneously
Leverage has slight bending;Zero toe-in is that wheel is directed straight ahead, and at this moment the abrasion of tire is minimum, and too big toe-in or posterior cord will
Lead to the abrasion of tire tread pattern edge pinniform, prenex excessive then worn tire tyre surface outside pattern edge, every skate tire
Decorative pattern internal edge is by pinniform;Posterior cord is excessive, and contrary tread wear effect occurs;The toe-in of therefore wheel exists
Most important during adjustment.
Auto producer domestic at present and car servicing centre are accurate when the toe-in to automotive wheel is adjusted
Property is not high, and the main cause causing this situation is that measuring apparatus are not right to the fixed form of automobile tire and measuring basiss,
Existing fixed form is to be folded on the wheel hub of automobile tire lateral surface using fixture, is entered on the basis of the wheel hub of automobile tire
Row measurement, so finally measure the measurement result that the toeing-in drawing is on the basis of wheel hub, rather than on the basis of tire
Real automotive wheel prenex, the measurement result on the basis of wheel hub is very big with the measurement result difference on the basis of tire,
Because contact with ground is tire rather than wheel hub, therefore, the automotive wheel toe-in result data that prior art is measured is not
Truly, inaccurate, the data result ultimately resulting in subsequently other measurement work is all untrue accurately, and impact is prenex to automotive wheel
Adjustment.
